Because people wrote them
Because there are too many stupid questions such as yours,
1) go to a category's main page 2) scroll down a little and you'll see three blue choices: unanswered, new questions, new answers. If you don't see those choices, then you're on a different kind of category page. In that case, scroll down, and on the far right of the page you'll see "see more activity" in blue. Left-click it, and in the page that comes up, you'll see a blue column on the left with "unanswered questions" as one of the choices.
